Predictive policing: Forecasting crime through data mining

Predictive policing, combines elements of traditional policing, like increased attention to crime “hot spots” and close monitoring of recent parolees. But it often also uses other data, including information about friendships, social media activity and drug use, to identify “hot people” and aid the authorities in forecasting crime, reported the New York Times.

The use of computer models by local law enforcement agencies to forecast crime is part of a larger trend by governments and corporations that are increasingly turning to predictive analytics and data mining in looking at behaviors. Typically financed by the federal government, the strategy is being used by dozens of police departments — including Los Angeles, Miami and Nashville — and district attorneys’ offices in Manhattan and Philadelphia.

But researchers working with the police to develop the predictive algorithms say that they can come closer than traditional detective work to figuring out who is most apt to break the law. They say criminals commit violent crimes in fairly distinctive patterns and often have similar attributes. Those include previous arrests; unemployment; an unstable home life; friends and relatives who have been killed, are in prison or have gang ties; and problems with drugs or alcohol.
